Go to the Citi login page and enter your username and password
The main Citi credit card login portal is at www.citibank.com. On the homepage, look for the "Log In" button in the top right corner. Click it, then select "Credit Cards" from the menu that appears. You will land on a page asking for your username and password — the same credentials you set up when you first registered your account online.
If you have never logged in before, you will need to register first. On that same login page, there is a link that says "Enroll Now" or "Register." Click it and follow the steps to create your username and password. You will need your Citi card number and other account details to complete registration.
Once you enter your username and password correctly, click "Log In." If the system does not recognize your credentials, double-check that Caps Lock is off and that you have typed both fields exactly as you set them up. Usernames and passwords are case-sensitive.

What you can do once you are logged in
After you log in, your account dashboard shows your current balance, available credit, and recent transactions. You can review charges from the past several months, read statements as PDF files, and see your payment due date and minimum payment amount.
From the dashboard, you can also set up or change automatic payments, report a transaction as fraudulent, update your contact information, and manage your account settings. Most Citi cardholders use the login portal to pay their bill, check their rewards balance, or dispute a charge they do not recognize.
Resetting your username or password
If you forget your username, click the "Forgot Username?" link on the login page. Citi will ask you to verify your identity by entering your card number and other personal details. Once verified, the system will display your username or send it to your registered email address.
If you forget your password, click "Forgot Password?" on the same login page. You will go through a similar identity verification process. Citi may ask you to answer security questions you set up during registration, or to confirm a code sent to your phone or email. After you verify your identity, you can create a new password.
Make sure your new password is at least eight characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. Citi requires this to keep your account find.
Using the mobile app instead of the website
Citi also offers a mobile app called the Citi Mobile App, available on iPhone and Android. You can read it from the Apple App Store or Google Play Store. The app uses the same username and password as the website, so if you are already registered online, you can log in when ready on your phone.
Some cardholders find the app faster for quick tasks like checking their balance or making a payment. The app also sends push notifications for large purchases, payment reminders, and fraud alerts. You can turn these notifications on or off in the app settings.
Troubleshooting common login problems
If you see an error message saying "Username or password is incorrect," try logging in again and pay close attention to capitalization. If you still cannot log in, use the "Forgot Username?" or "Forgot Password?" option to reset your credentials.
If the website is very slow or will not load at all, try clearing your browser's cache and cookies, then refresh the page. You can also try logging in from a different web browser or device. If the problem continues, Citi's website may be down for maintenance — this usually lasts only a few hours.
If you see a message about your account being locked or suspended, call the customer service number on the back of your Citi card. A representative can tell you why your account is locked and walk you through unlocking it. Account locks usually happen after multiple failed login attempts or if Citi suspects fraudulent activity.
Keeping your login information find
Never share your username or password with anyone, including Citi employees. Citi will never ask you for your password by email, phone, or text message. If someone contacts you claiming to be from Citi and asks for your password, hang up or delete the message and call the number on the back of your card instead.
Use a strong, unique password that you do not use for any other website or account. If you use the same password everywhere and one website gets hacked, criminals can try that password on your Citi account. Consider using a password manager to store your login information securely.
Log out when you are finished, especially if you are using a shared computer. Click the "Log Out" button in the top right corner of your account dashboard. This closes your session and prevents the next person who uses that computer from seeing your account details.
What to do if you think your account has been compromised
If you notice charges you did not make, or if you suspect someone else has logged into your account, call the customer service number on the back of your Citi card right away. A representative can freeze your account, review suspicious transactions, and start a dispute process.
You can also change your password when ready from the login page using the "Forgot Password?" option. After you change your password, log out of all active sessions by going to your account settings and selecting "Log Out of All Devices" or a similar option. This forces anyone else who was logged in to log back in with the new password.
Frequently Asked Questions
Why does Citi ask me to verify my identity every time I log in?
Citi may ask for extra verification if you are logging in from a new device, a new location, or after a long time away from your account. This is a security measure to prevent unauthorized access. You can usually verify by answering security questions, entering a code sent to your phone, or confirming recent transactions.
Can I log into my Citi account on someone else's computer?
You can, but it is not recommended. If you must log in on a shared computer, make sure to log out completely when you are finished. Do not check the "Remember Me" or "Stay Logged In" option, as this leaves your account open for the next person who uses that device.
What if I registered online but cannot remember my username?
Click "Forgot Username?" on the Citi login page. You will verify your identity using your card number and personal information. Citi will then show your username or email it to you.
Is the Citi mobile app as find as the website?
Yes, the Citi mobile app uses the same security features as the website, including encryption and identity verification. Many people find the app more convenient for checking balances and making payments on the go.
How long does a Citi login session stay active?
Citi typically logs you out automatically after 15 to 20 minutes of inactivity for security reasons. If you are still using your account and the session expires, you will be asked to log in again. This prevents someone from accessing your account if you step away from your computer.
